The behavior of water in molten salts
The different behavior of water equilibrated with three separate molten salt solvents is discussed with respect to the chemistry of the solutions and the electroreductive mechanisms at gold electrodes. In the case of the equimolar mixture of KNO/sub 3-/NaNO/sub 3/, water dissolves without chemical reaction with the solvent in contrast to the behavior in the Li/sub 2/SO/sub 4-/Na/sub 2/SO/sub 4-/K/sub 2/SO/sub 4/ (78-8.5-13.5 mole percent (m/o)) and the Li/sub 2/CO/sub 3-/Na/sub 2/CO/sub 3-/K/sub 2/CO/sub 3/ (43.5-31.5-25 m/o) where reaction to form bisulfate, bicarbonate, and hydroxide takes place. The mechanism of the reduction of water in the nitrate melt is shown to take place by means of parallel E/sub 1/C/sub 1/E/sub 2/ and E/sub 1/C/sub 2/ pathways in which E/sub 1/ < E/sub 2/.
